Issabella and Ella - thank you. Just trying to see if GIMP can compete with Blender results :lol:

Diego - please feel free to comment; I do realise there are still improvements to be made and your experienced comments are valued :D

OMG, would you share how you start to make the mug? I'm not sure how to begin. Your's and Ella's are really nice. I have not attempted Blender and probably will never get around to doing so. I would like to try it in GIMP.

OMG, my comments are those you would expect from me: wonderful rendering technique but..a weak perspective.
A couple of images to illustrate.

Diego - thank you very much ... it is so obvious when I look at both your diagram and reworking of mine. Yes, I should kick myself because I had a feeling about just that perspective issue and the base of the mug when I had finished it. My focus was too much on the lip/rim problems at the top, but I should have identified and fixed the perspective issue at the bottom, especially after your schooling me on just that matter some time back.

Thanks again Diego for your constructive comments. :)

EDIT : just downloaded 3 manuals to help reinforce how to get my perspectives correct; given that I used an ellipse for both top and bottom of the mug, the paragraph below really caught my eye. So never stop learning eh!!.

Any artist can tell you how tricky it is to draw ellipses in perspective. The top of the flower pot, the lid on a jar, the base of the barn silo —
whether it’s a still life or a landscape, you’re bound to encounter the challenge of depicting a foreshortened circle, or ellipse, in just about
any drawing or painting. Most of us try to “eyeball it” in the hopes that it’ll be good enough, but there’s an easier and more correct way of
getting it just right.

OMG, dont know what dinasset has to say, he's a master gimper and I'm a dilettante.
OMG, told you so, Diego has the eye of a master.
I can only comment a detail in the whole, with the eye of a dilettante. Diego sees the complete picture, with the eye of a master.
Thank you both for the enlightening explanations.

Constructive comments, that's what we need to keep on learning.

Pat - I'll outline how I start doing the mugs, but you will have seen that a 'lot of water has passed under the bridge' since you posted your request.

Remember this is how I did it and I have no training/knowledge of proper artistic techniques although after 2 days of going through perspective manuals, I would certainly incorporate those drawing techniques next time (see viewtopic.php?f=8&p=10365#p10365 ).

However, back to your request -

1. I drew the mug shape using a number of paths - image 1 below
2. I filled the path shapes with the colour I choose for the mug
3. Then I drew a number of paths (image 2) to help me with the light/shadow effects on the mug
4. I used a variety of tools for light/shade and emphasis of the curves on the mug -
- BRL for the handles
- Chisel or carve
- Gradient blend black or white or a darker hue of the mug colour using foreground to transparent
- also used Gaussian blur at times on those gradients

Hope this helps Pat, but there are probably better ways to do it.

Thank you very much, OMG. This is helpful. I just did not know how to get started. I'll give it a try. Don't suppose I'll get the perspective correctly, do you? :lol: :P
